COMBINATION ROTARY AND CABLE TOOL DRILLHTG- RIG.

Application filed October 28, 1920. Serial 110. 420,282.

California, have invented .certain new and useful Improvements ln Comblnatron R tary and Cable Tool Drilling Rigs. of which the following is a specification.

The objects of my invention are, first to construct a combination drilling rig that is adapted to decrease the ground area necessary to operate the same, and that will re-' quire only one side of the derrick, to eliminate the useof bull ropes or chains over the derrick floor, to'increase the clear space thereon, and to adapt the housing inof all chains and belts. second -;-to use an imroved type and arrangement of power transmission, with-a swiveled-walking beam that is adapted to facilitate the'op'eration of a cable tool rig'withoutthe disconnection of the parts thereof, third ;to use an interchangeable rig of the said class that may be 'driv'enby 'a single power unit of any description .for'drilling oil, gas, or water wells, fourth ;to use a power transmission means that is adapted to reduce the size of all sprockets to less than fifty teeth, and to eliminate the use of wood in the construction of the same, to increase the strength and prevent deterioration.-

Further objects are to drive the rotary machine, which is used for hydraulic drilling, by a shaft the same as the present shaft drive attachment except that the power" is applied directly at the end of the rotary unit by driving the hoisting drums by I driving shaft, and is mechanically controlled so that the rotary machine may be stopped independently of the engine, or motor.

The present type drum for the draw works is keyed to its shaft, and it is found that the three bearings used are difficult to ,keep in alignment, and if kept rigidly adjusted will create undue friction on the shaft necessitat- .ing the use of extra. heavy snatch blocks to bring the hook and elevators down at a pre-' My calf wheel, or works, is controlled similarly, to. the present draw works, with clutches of the bevel j aw type arranged so that the high speed can take the load from the low speed by automatically throwmg out the low'speed clutch, or vice versa. My draw works, which I also use as a calf wheel is located in the present calf wheel position to dispense with the .present type of draw works now in'common use on the Sside of the derrick; and-I place my bull Wheel beside the calf wheel which is driven thru the calf wheel shaft to replace the present dangerous rope driven bull wheel on the E side of'the derrick, thus eliminating the obstructionon the derrick floor and sides, and to convenience the handling of drilling materials.

Mysand reel is driven by a friction clutch, and is controlled by'a band brake to overcome the excessive wear of the rope lagged clutch on the walking beam crank shaft, I

can use my balanced crank shaft with the bearin s on close centers to obtain a more rigid rive, and I in turn locate my sand reel so that its shaft is used as a counter shaft for obtaining the required speed reduction, to operate the said walking beam.

I eliminate the use of more than one power 7 sprockets and a chain direct from .the'en 'ne for a low speed. I applythese drives by clutches on the line shaft, and when disengaged I can operate the cat heads in the usual manner. My drums are soarran ed that they can run freely on their shafts w on lowering drill pipe, casing, or tools, and so that they in turn revolvewith the shaft when pulling a load.

I use a crown block, not shown, on the top portion of the derrick 85, consisting of p elevators, not shown. The snatchblock.

sheaves and crown block sheaves are adapted to give a predetermined load reduction on the calf wheel 7. The said calf wheel 7 in connection with a high speed drive becomes a draw works, for a hydraulic-rotary drilling machine, to raise and lower drill pipe, and is adapted to use the same crown block connection therewith. A sand line,'

not shown, is run from the sand.reel 42, over the said sand line sheave, and connects directly to abailer or sand pump, no shown.

With the foregoing objects'in view, the invention resides in the combination of details and construction hereinafter described and claimed.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which: I

pulley 40 is secured on the shaft 34, and is' connected to the pulley 39 of the said engine 1 by the belt 25, the clutch 55 is mounted on the shaf 27 and is adapted to drive the clutch-sprocket 11, the sand reel 42 is operatively mounted on the said shaft 27, the clutch 89 is also mounted on the shaft 27 and is adapted to drive the. sand reel 42, the brake 43 is in turn mounted on 'the sand reel 42. The shaft 28 is adapted to be operatively mounted on the jack posts 62, the sprocket 12 and the counterweight 41 are securely mounted thereon, the chain 23 is adapted to operatively mesh between the sprockets 11 and 12, the crank 64 is in turn secured to the outboard portion ofthe shaft 28.

The samson post 63 is mounted on the main sill 87, and is adapted to accommodate t-ively mounted on the bearings 66 and is integral with the saddle 71, the walking beam 57 is in turn secured on the saddle 71, the bearings 75 are integral with the cap and the said bearings are in turn adapted to receive the worm 73 therebe tween, the shaft 76 is operatively positioned in the bearings 75 and is secured to the worm 73, the worm gear 74 is integral with the bearing 66, and is adapted to mesh with the worm 73, and the sheave 69 is securely mounted on the shaft 76 and is adapted to accomodate the chain 70.

A modified form of power transmission may be applied by omitting the bevel gear 48, the bevel pinion 49, the sleeve 56, and

the rotary machine 6, for cable tool drilling,

chain 22 direct from the engine, the clutch 52 with the coupling 37 disengaged is adapted to control the slowspeed operation of the draw works, (which comprises the shaft-31 with all the mechanism thereon) thru the sprocket 18, the chain 21, and the sprocket 19' respectively, and the clutch 51 is in turn adapted to control the operation of the said draw works when a high speed is desired by transmitting the power thru the sprocket 14, the chain 20, and the sprocket 15 respectively. I can also use my combination rig for cable tool drilling, with the operation of my calf wheel 7, and bull wheel 8, by engaging the clutch 50 (with the bevel gear 48. the bevel pinion 49 and the rotary machine 6 removed) to drive the shaft 29, thru the sprocket 10, the chain 22, and the sprocket 13 respectively, the power is thence transmitted to the said calf 'wheel 7 (or draw works), in like manner as when used for rotary drilling.
